Capella,also assigned Alpha Aurigae (α Aurigae, shortened Alpha Aur, α Aur), is the brightest star within the star grouping of Auriga, the sixth-brightest within the night sky, and the third-brightest within the northern celestial hemisphere after Arcturus and Vega.

A prominent star within the winter sky of the northern side of the equator, it is circumpolar to eyewitnesses north of 44°N. Its title meaning "small goat" in Latin, Capella portrayed the goat Amalthea that suckled Zeus in classical mythology. The Capella framework is generally near, at as it were 42.9 light-years (13.2 pc) from the Sun. Although it shows up to be a single star to the bare eye, Capella is really a framework of four stars in two parallel sets.

The primary match comprises of two shinning yellow mammoth stars, both of which are around 2.5 times as gigantic as the Sun. They have depleted their core hydrogen, and cooled and swollen, moving off the most grouping. Assigned Capella Aa and Capella Ab, they are in an awfully tight circular circle a few 0.74 as apart, and orbit each other every 104 days.

Sirius A is about twice as massive as the Sun (M_☉) and has an absolute visual magnitude of +1.42. It is 25 times more luminous than the Sun but has a significantly lower luminosity than other bright stars such as Canopus or Rigel. The system is between 200 and 300 million years old.^[12] It was originally composed of two bright bluish stars. The more massive of these, Sirius B, consumed its resources and became a red giant before shedding its outer layers and collapsing into its current state as a white dwarf around 120 million years ago.

Sirius appears bright because of its intrinsic luminosity and its proximity to Earth. At a distance of 2.6 parsecs (8.6 ly), as determined by the Hipparcos astrometry satellite,the Sirius system is one of Earth's near neighbours. Sirius is gradually moving closer to the Solar System, so it will slightly increase in brightness over the next 60,000 years. After that time its distance will begin to increase and it will become fainter, but it will continue to be the brightest star in the Earth's night sky for the next 210,000 years

Vega star is the fifth-brightest star in the night sky and the second-brightest star in the northern celestial hemisphere (after Arcturus). Vega is also known as Alpha Lyrae (α Lyrae, Alpha Lyr, α Lyr), as it is the principle star in the constellation Lyra, the lyre. Vega has been one of the most important stars to humanity since ancient times because it is very bright and easily recognized by its blue color.

Quark stars have some special characteristics that separate them from ordinary nucleon stars.

Under the physical conditions found within nucleon stars,with extremely high densities however temperatures well below 1012 K, quark matter is predicted to exhibit some peculiar characteristics. It is expected to behave as a Fermi liquid and enter a so-called color-flavor-locked (CFL) part of color electrical conduction, where "color" refers to the six "charges" exhibited in the strong force, instead of the positive and therefore the negative charges in electromagnetism. At slightly lower densities, corresponding to higher layers closer to the surface of the compact star, the quark matter will behave as a non-CFL quark liquid, a phase that is even additional mysterious than CFL and may embody color physical phenomenon and/or many further nevertheless undiscovered phases. None of these extreme conditions can presently be recreated in laboratories thus nothing are often inferred regarding these phases from direct experiments.If the conversion of neutron-degenerate matter to (strange) quark matter is total, a quark star can to some extent be fanciful as a single mammoth elementary particle. But this "hadron" can be sure by gravity, rather than the interaction that binds ordinary hadrons

Neutron star are the corpses of star at 12 to 15 miles across and completely full of neutrons. A neutrons stars are so dense that a cubic centimeter weighs a million metric tons. When two neutrons star collide, they would generate the elements such as Platinum, Uranium and gold. In 2017, astronomers observed two stars slamming into each other deep in space at a hundred and thirty million light years away. The huge explosion rippled the fabric of universe caused the distortion space-time.
